My petcock leaks.- I have the replacement 'biscuit' & I need to drill out the rivets on the cover plate to replace it.
When I tear My tank apart to paint it. I want to check the vacuum diaphragm on the petcock because I think its failing on occasion. The bike will warm up & shut off abruptly. Seems like the gas gets shut-off suddenly B-550 On 04/19/12, Kyle Munz wrote: If everything is correct the vacuum line should be hooked up to the horizontal port. Basically, if the fuel line is off the carb, the gas cap is open, the fuel cock is in ON or RES, and you apply vacuum to that port, gas should poor out of the fuel line. If it doesn't, then your fuel cock is clogged, or you're out of gas. Assuming you do have gas in the tank, I would recommend cleaning the fuel cock. It's really not that hard if you take your time and are careful around the rubber diaphragm. I took pics when I cleaned up one on my 650, not the same bike but should be close enough for you to follow. http://www.kylemunz.com/nighthawk/?p=151 -Kyle On Thu, Apr 19, 2012 at 8:09 PM, shay's nighthawk <[email protected]> wrote: I do not see how to post pics but I have them in and album on picasa. try these links https://picasaweb.google.com/109828126930056558938/DropBox#5733281638663420962 https://picasaweb.google.com/109828126930056558938/Petcock#5733280961831913538 On Apr 19, 5:55 pm, "shay's nighthawk" <[email protected]> wrote: > Hi again > Thanks to everyone for your input.
